A man in Zhubei has been indicted for sending a bomb threat to Taiwan's high speed rail operator, a case that briefly raised safety fears across stations and trains.

• The message, sent in April through the rail company's online customer service chat, claimed there really was a bomb on the high speed rail.
• He sent it from his own computer at his workplace in Hsinchu County, using a browser's private mode to try to stay hidden.
• Railway police tracked him down anyway, and prosecutors in Taoyuan have now formally charged him.
• The charge falls under Taiwan's railway law for threatening or obstructing rail staff, carrying up to three years in prison and a fine.

Outlook: The case now moves to court, where a conviction would send a warning that anonymous online threats against transport operators are still traceable.
